<!--quirks mode-->

<!--
  It's not clear that this is desired behavior, but I'm adding a test
  for it because bug 243519 *accidentally* regressed it.

  We're testing here that quirks mode percentage height calculation
  subtracts the margin, padding, and border of the BODY element when the
  basis for that percentage height is a specified non-auto height on the
  HTML element.
-->
<html style="height: 300px;
             margin: 1px 0 2px 0; padding: 4px 0 8px 0;">
<head>
  <title>Testcase, bug 471356 / bug 243519</title>
</head>
<body style="margin: 16px 0 32px 0; padding: 64px 0 128px 0;">
  <!-- basis for percentage is 300px - (16px + 32px + 64px + 128px)
         == 60px -->
  <div style="background: blue; height: 50%">
  </div>
</body>
</html>
